摘要： A process for the manufacture of a fibre web containing a thermosetting resin, and a reinforced thermosetting resin composite containing the fibre web containing the thermosetting resin. The process comprises forming a fibre web of at least reinforcing fibres, bringing at least a thermosetting resin together with the reinforcing fibres, and joining the fibre web at least partly by means of said thermosetting resin. Further, the process comprises having the thermosetting resin in the form of substantially dry grains, bringing said grains of thermosetting resin together with the reinforcing fibres at a confluence temperature at about room temperature, and then joining the fibre web by prior to and/or under a pressure at least partly heating the grains of thermosetting resin present in the fibre web to a joining temperature being higher than the temperature at the confluence and then cooling the fibre web to room temperature. The reinforced thermosetting resin composite can preferably be used for sanitary products such as washing basins, toilet chairs, for different abrasive surfaces, for electrically conducting products and for medical technical products such as implantable devices for lengthening of a leg and the similar. Many other applications are considered as well.

摘要： Described are very high molecular weight (e.g., over 2 million, such as 3-20 million g/mol) starch-based materials, and formulations including such, which can be spun in spunbond, melt blown, yarn, or similar processes. Even with such very high molecular weights, the formulations can be processed at commercial line speeds, with spinneret shear viscosities of 1000 sec−1, without onset of melt flow instability. The starch-based material can be blended with one or more thermoplastic materials having higher melt flow index value(s), which serve as a diluent and plasticizer, allowing the very viscous starch-based component to be spun under such conditions. The particular melt flow index characteristics of the thermoplastic diluent material can be selected based on what type of process is being used (e.g., spunbond, melt blown, yarn, etc.). The starch-based material may exhibit high shear sensitivity, strain hardening behavior, and/or very high critical shear stress (e.g., at least 125 kPa).

摘要： A process for producing a deformed nonwoven is described. The process includes the steps of: adjusting a water content of a nonwoven such that the nonwoven has at least one area having a water content of at least about 12% by weight of the nonwoven in the area, and subjecting the nonwoven to a mechanical deformation process. The deformation process is a mechanical deformation of the nonwoven and dewatering of the nonwoven to obtain a deformed nonwoven.

摘要： The present invention relates to a method of producing a ribbon comprising bamboo fibers. The method comprises positioning the fibers on a conveyor and conveying the fibers in a transport direction, interconnecting the fibers by covering the fibers with thread and/or particles of a sticky material with at least one web forming device which is positioned above and/or below the conveyor and which ejects thread and/or particles. The formed thread and/or particles attaches to the fibers and forms a web which interconnects the fibers in order to form the ribbon and/or stitching the fibres together with at least one stitching device which is configured to stitch the individual fibers together in order to form the ribbon.

摘要： A system having a first polymer source and a spin beam in fluid communication with the first polymer source is provided. The spin beam includes a spinneret assembly having filament nozzles configured and arranged to extrude a plurality of filaments of a first polymer. A gas distribution plate is disposed downstream of the spinneret assembly, and includes a plurality of gas distribution slots that are configured and arranged to receive two or more corresponding filament nozzles of the spinneret assembly therein. A stream of gas is introduced into the plurality of slots to draw and attenuate the filaments extruded by the plurality of filament nozzles. The drawn and attenuated filaments are collected on a collection surface disposed downstream of the gas distribution plate to form a nonwoven fabric. A solid additive, such as pulp fibers may be blended with the filaments prior to collecting the filaments on the collection surface.
